EDWIN BALL STIMPSON, 0F BROOKLYN, NEVT YORK, ASSIGNOB TO EDWIN B. STIMPSON COMPANY, A. CORPORATION OF NEW YORK.

MACHINE FOR OREASING LEATHER AND THE LIKE.

lb all whom it may concern:

Be it known that I, EDWIN B. S'rmirsoN, a citizen of the United States, residing in the borough.- of Brooklyn, in the county of Rings, in the city and State of New York, have invented certain new and useful Improvements in hfachines for creasing Leather and the Like, of which the following is a specification.

This invention relates to the class of machines employed in marking leather and the like although certain features of it are not limited to machines of this character as will appear from the claims.

In the accompanying drawings, which illustrate one of the embodiments of the invention-Figurc l is a front elevation of the machine; Fig. 2 is a plan thereof; Fig. 3 is an end elevation thereof; Fig. 4 is a V j -vertical transverse section at line m 111 Fig.

l; and Fig. 5 is a plan view at a? in Fig. 1, the parts seen above this line being omitted in Fig. These general views are on a relatively small scale. Fig. 6 is a detail side elevation of the creasing or marking de vice on a relatively large scale, the adjacent parts of the machine being in section at line as in Fig. 1; and Fig. 7 is a view on the same scale showing the creaser in diametrical section. Fig. 8 is an end-view showing ona larger scale the parts seen in Fig. 3. In this view some of the parts are cut away at line to in Fig. 9. Fig. 9 is a plan view on the same scale as Fig. 8, the parts above line a" in Fig. 8 being omitted. Fig. 10 is a detail view of the post 11.

The specific object of this machine is to produce permanent marking creases in leather by means of heated creasers; and by it parallel creases may be produced simultaneously by any number of such heated creasers set at any desired distance apart. The creasers are also made adjustable so as to produce the desired depth of the crease.

The creasing or marking face of the creaser may be of any design required; this is not material to the present invention.

1 designates a suitable frame carrying a work-supporting table 2, a driven bed-roller 3, and a driving pulley It will be sufficient to state that the pulley e is rotatable on a short shaft in the frame and may be clutched to the shaft at will by means of an Specification of Letters Patent.

ordinary clutch-device 5 (Fig. 9) operated by a lever 6. On the pulley-shaft is a pinion T, which gears with a similar pinion '8 on the bed-roller 3. Through this mechanism the roller 3 is driven at the desired speed. The upper surface of the roller 3 is nearly on a level with the supporting table On the frame 1, at its respective ends, are fixed upright columns 9, on which is slidably mounted and guided, a head 10,

made adjustable up and down with respect to the bedroller 3, or toward and from the same, by means now to be described.

At each end of the machine is an upright post 11, (seen detached in Fig. 10) which is splined in a lug 12 on the frame and has a collar 11 that bears on said lug. On the lower end of this lug is a somewhat compressed strong spring 13, embraced between said lug and nuts let on the screw-threaded lower end of the post 11. This spring holds the collar 11 drawn down yieldingly but firmly against the upper surface of the lug 12. The upper portion of the post 11 above the collar, is screw-threaded and on this portion is a wormwheel nut 15, embraced and collared snugly between two lugs 16 on the end of the head 10, the threaded post playing through apertures in said lugs. On a shaft 17, rotatively mounted in hearings on the head 10, are fixed worms or screws 18, which gear with the respective worm-wheel nuts 15, said shaft being rotated by a suitable hand-wheel or crank 19, for adjusting the head 10 up or down.

It will be noted that the posts 11 are held normally stationary by the strong springs 13, and that by rotation of the nuts 15 the head 10 may be raised or lowered to a limited extent as though the said posts 11 were actually fixed; but the postsand with. them the head l0may be lifted when desired by means best seen in Figs. 1, 3 and 8. In the frame below is a horizontal rod 20, on which is mounted a treadle 21; and a rod 22 from this treadle extends up and is coupled at its upper end to an arm 23, fixed on a rockshaft 2a in the frame. Thus the shaft 21 is rocked by the treadle. On the shaft 24: are secured two toes or lifters 25,

which take under the lower ends of the respective posts 11, so that, by means of the treadle the head 10 may be raised and lowered at the will of the operator without disturbing its adjustment.

The creasing or marking device, of which there may be one or more mounted on the head 10, will now be described. As seen best in Figs. 6 and 7, the marking or creasing device comprises a base-piece 26, having a square boss on its upper face that engages a longitudinal groove in the lower face of the head 10, this base-piece being secured removably and adjustably to the head by means of a screw 27, which extends down through a longitudinal slot 28 in the head. Hinged at 29 to the base-piece, is a. creaser 30. The upper part of the creaser has a rib or tongue 41 (Fig. 7) on its upper edge, which engages a corresponding groove in the lower face of the base-piece 26, to prevent any lateral vibration or lateral movement of the creaser; and a spring 32 connects the creaser with the base-piece and tends to depress the former, the extent of depression being, however, regulated and limited by a screw 33, which plays in a hole in the base-piece and is driven into the creaser. The purpose of this special construction will be hereinafter explained. Obviously the creasing or marking devices may be shifted along the head 10 and set thereon by the screws 27 in any positions desired.

In order to heat the creaser 31 a gas burner 34 is provided, and this burner supplied with gas through a flexible tube from any source of As herein shown, there is a flexible tube extending from each creasing device to a gas-pipe 36, supported in suitable brackets on the head 10, this pipe being supplied from any source by a tube 37 Each tube 35 will be controlled by a cock of the usual kind.

Obviously any means for supplying gas for heating the creasers or markers, or any manner of heating the latter, may be employed. That shown is convenient. The operation will be readily understood. The machine is prepared by setting and fixing the creasing devices at the proper distances apart along the head 10; the head is adjusted vertically to adapt the creasers to the thickness of the materials to be creased or marked and to get the proper depth of impression, and the burners ignited to properly heat the creasers. To make some of the creases deeper than others, the corresponding creasing devices are individually adjusted accordingly. The roller 3 is then setin motion by means of the clutch-lever and the material (L in Fig. 6.) fed in under the creases. The spring 32 combined with the adjustable connection 33 between the hinged parts of the creasing device, governs the extent of the individual impressions and should there be, for example, a hard and relatively unyielding spot in the leather or other material, this spring will permit the creaser to yield a little. But the spring will be strong enough to effect the impression desired in any chosen material. It will be noted that each creaser may yield and may be adjusted independently.

The springs 13 are designed to be so strong as not to yield to any pressure required for making the creasing impression, but to yield only to the operation of the treadle. latter lifts the head and creasers so that the material may be entered and taken out, and so that the creasing may be arrested instantly at any point desired.

Obviously the invention is not restricted to the specific mechanical elements herein shown as these may be varied or substituted without departing in any material degree from the invention.

The bed-roller 3 is a feeder for the material 14 to be creased or marked, and this material may be of any kind suitable for creasing, printing, embossing or scoring. The marking face of the creaser may, of course, have any contour or form adapted for producing the kind of crease or mart. desired. That shown is a simple form.

Having thus described my invention, what I claim is:

1. In a creasing machine, the combination of a head having a slot lengthwise thereof, a rod in said slot adjustable along the length. thereof and adapted to be fixedly secured therein, and a creasing device carried by said rod having a boss engaging the sides of the slot in the head and prevented thereby from turning.
